A Portfolio of Original Compositions (Andrew Dolphin)
Sound toys as open work, composition medium and compositional tool. A collection of interactive sonic centric audiovisual systems, designed and influenced by aesthetics, processes and techniques familiar to the field of electroacoustic music, and informed through the composition and realisation of …

Soundscape Ecology of Hawaiian Spinner Dolphin Resting Bays
… is a key sensory modality for Hawaiian spinner dolphins. Like many other marine animals, these dolphins rely on sound and their acoustic environment for many aspects of their daily lives, making it is essential to understand soundscape in areas that are critical to their survival. Hawaiian …

A stochastic measure of similarity between dolphin signature whistles
… modeling to automate the comparison of dolphin whistles and to yield an objective, quantitative measure of whistle similarity. The relationship of bottlenose dolphin whistle production to a model of human speech production is discussed, providing a basis for the use of human speech …

Passive Turbulent Boundary Layer Control through 3D-Printed Dolphin Skin
… grooves modeled after the Atlantic bottlenose dolphin (Tursiops truncates) skin to mitigate boundary layer separation as a form of passive flow control, energizing the flow near the wall. A water tunnel generates a tripped turbulent boundary layer across a vertical test plate, and a rotating …

Population structure and genetic variation in Hector’s dolphin (Cephalorhynchus hectori)
… structure and genetic variation in Hector’s dolphin (Cephalorhynchus hectori), to track population declines and to assess the evolutionary origins and taxonomic status of this species. A high-resolution genetic analysis of population structure was considered important for the determination of …

An Investigation of Dolphin-Groove Inspired Surface Patterning on Flow Control
… could result from the micro-grooves found on dolphin skin (Tursiops truncates). A water tunnel was used to study a turbulent boundary layer over rigid 3D printed plastic models, and an adverse pressure gradient was created with a rotating cylinder to induce flow separation in the region of …

Does Personality Similarity in Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?
… bond components and is yet to be demonstrated in dolphins. This study utilizes a captive population in a naturalistic environment to test for correlation between similarity within the dyad along each personality factor and the strength of the dyad’s bond characteristics. Personality was assessed …

Generic compression and recall of signals with application to dolphin whistles
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 1993.

Relating behavioral context to acoustic parameters of bottlenose dolphin (Tursiops truncatus) vocalizations
… the function of vocalizations of the bottlenose dolphin, Tursiops truncatus. The thesis uses the social interaction as the basic unit of analysis, and maintains a deliberate focus on quantitative and replicable analyses throughout. A method for determining identity of the vocalizing animal in a …

Genetic Dispersal Patterns in Cetaceans: The Development of Dolphin, Whale, and Porpoise Subpopulations
Population genetics is the study of allelic distributions and frequency changes in populations. It has been used to assess dispersal patterns within cetaceans. A literature review was conducted on dispersal patterns and population genetics to determine dispersal patterns such as sex-biased …

Personality and affiliation involving a cooperative task in bottlenose dolphin (Tursiops Truncatus) Dyads
… may be related to personality in bottlenose dolphin (Tursiops truncatus) dyads. Five bottlenose dolphin pairs at the Roatan Institute for Marine Sciences (RIMS), Honduras, were presented with an apparatus released a food reward if opened cooperatively. I created personality profiles of each …

Solitary and Social Object Play in the Bottlenose Dolphin (<i>Tursiops truncatus</i>)
… calf, juvenile, subadult, and adult bottlenose dolphins (<em>Tursiops truncatus</em>). While juveniles engaged in solitary play significantly more than any other age group, both juveniles and calves engaged in observer and social play significantly more than adults and subadults. Within their …

Investigation into the Neurogenetics of Vocal Learning in Tursiops Truncatus, the Bottlenose Dolphin
… reference genome assembly for the bottlenose dolphin (<em>Tursiops truncatus</em>). Bottlenose dolphins are well-documented learners that share significant phenotypic overlap with human language development. Using a trio binning approach developed by the Vertebrate Genome Project (VGP), in …

The Importance of Bioacoustics for Dolphin Welfare: Soundscape Characterization with Implications for Management
<p>Sound is the primary sensory modality for dolphins, yet policies mitigating anthropogenic sound exposure are limited in wild populations and even fewer noise policies or guidelines have been developed for governing dolphin welfare under human care. Concerns have been raised that dolphins under …

Effects of Failure on Subsequent Performance in the Bottlenose Dolphin (<i>Tursiops truncatus</i>)
… based training sessions in 11 bottlenose dolphins (<em>Tursiops truncatus</em>) at the U.S. Navy Marine Mammal Program in San Diego, CA. While learning a multi-faceted behavior not commonly found in nature, such as beaching, animals are likely to perform approximations of the behavior that …

Boat preference and stress behaviour of Hector's dolphin in response to tour boat interactions
Dolphins are increasingly coming into contact with humans, particularly where tourism is involved. It has been assumed that such contact causes chronic stress on dolphin populations. This study examined relatively naive populations of Hector's dolphins and their interaction with various …
